Installing Progressive fork springs (Gunny)
Submitted by Gunny of the VTXOA What you’ll need – One set of Progressive Fork Springs Torque Wrench 17mm Socket Head 17mm Closed End Ratchet Wrench (Real handy tool since working around the fork cap can be tight.) 6mm Torx wrench socket (it’s an Allen Wrench head – but they call them Torx heads. I bought a full metric set from Northern Tools that fits my ¼” socket wrench – real handy when working on the beast.) A good bike lift Start by lifting the bike – you want the front wheel completely off the ground. Lay a towel over the front fender – and have several shop towels ready – you WILL drip some fork oil off the old springs when you pull them out. There are some wire anchors set under the bars over each fork cap. They slide off the metal anchor point towards the center of the bars. This gives you just enough room to use the torque wrench later. (Don’t worry – they slide right back on when you’re done.) Doing one fork start to finish at a time – With the 6mm Torx Head socket and a socket wrench loosen the upper pinch bolt just enough to take the pressure off the fork cap. It is the pinch bolt located just below and to the rear of the fork cap. (You only need to loosen it about 1 turn.) Using the closed end self ratcheting 17mm wrench slowly loosen and remove the fork cap. (Keep in mind that the fork spring is pushing up on it from below – keep pressure down on it with your palm as you unscrew it or it may just join the Chinese in orbit!) Once the Fork Cap is removed take the 4” spacer out of the fork and lay it on a clean towel on the floor. Stick your finger into the fork and remove the small metal washer that’s lying on top of the spring. Lay it next to the spacer. Slowly remove the spring – you can bend it forward to clear the bars and slowly pull it out. Keep a shop towel around it as you pull it out as it will be dripping with fork oil. Insert the new Progressive Spring into the fork. Although Progressive says it doesn’t matter go ahead and insert it with the closely packed end in first. Put the metal washer in the fork – laying it on top of the spring. Put the 4” spacer back in the fork on top of it all. Now the fun part – pushing down on the fork cap to seat it in the fork tube use the 17” self ratcheting wrench to screw it back in. (Here’s where you find out that the socket wrench is to big – but a self ratcheting wrench is perfect for this. It takes some force to push it all in and seat it – just take your time and don’t force it if the threads don’t seat properly. Just back out and start again. Once it’s screwed in (don’t screw it real tight) – use the 17mm socket head and the Torque Wrench to tighten it to 17 lbf-ft. Using the 6mm Torx head socket and the Torque Wrench tighten the Upper Pinch Bolt to 17 lbf-ft. Reattach the wire anchor on the bottom of the bars. Clean up any drops of fork oil. Repeat above on the other fork. It sounds like a lot – but I did it in about 30 minutes and am admittedly mechanically inept. Enjoy the ride. GUNNY
